HVAC | Damen ASD Tugs 3213

The Damen ASD Tug 3213 is designed to be highly manoeuvrable, sail in choppy seas with no loss of stability and operate in a very environmentally friendly way.

Challenges

The challenge for Heinen & Hopman was to design a standard plug-and-play compact air handling/condensing unit and ensure in all circumstances an indoor temperature of 20 °C, 50% RH at 50 °C, 40% RH outdoors.

Scope of work

Heinen & Hopman’s scope of work for this series of vessels was the design and equipment delivery. Equipment supply included all parts of the air conditioning and mechanical ventilation system, including the control panel. For the wheelhouse and accommodation, an air conditioning system was selected with one air handling unit with an optional heating section and one seawater-cooled condensing unit built together on a common frame. The wheelhouse has its own temperature control system (Variable Air Volume system) and temperature controlling is independent of the rest of the system.

Thanks to the VAV system in the wheelhouse, the ventilator of the air handling unit is speed controlled by a frequency drive. In addition, there is a separate air conditioning system serving the main engine control room, consisting of a seawater-cooled condensing unit and direct expansion air handler.

Scope of supply:

• One air handling/condensing unit package in accommodation
• One condensing unit with direct expansion air handler
• Three axial flow fans
• Six centrifugal duct fans
• One galley extractor hood
• Fire dampers and smoke dampers
• Cabin units
• Punica louvres
• Mist eliminators
• Sand filters serving engine room
• Control panel
• Frequency drives
• Variable Air Volume system in the wheelhouse
